我想对AJAX请求的结果进行分页。分页不起作用。单击页码后，只有地址和所有内容（例如：/ page / 3 /）发生变化。我在哪里弄错了？
page.php文件
<div class="site-content clearfix">
<h1>Alex Blog</h1>
<?php
$ourCurrentPage = get_query_var('paged');
$aboutPosts = new WP_Query(array(
'post_type' => 'tour',
'post_status' => 'publish',
'posts_per_page' => 3,
));
if ($aboutPosts->have_posts()) :
while ($aboutPosts->have_posts()) :
$aboutPosts->the_post();
?>
<span> <?php the_title(); ?> </span>
<br>
<?php endwhile;
echo paginate_links(array(
'total' => $aboutPosts->max_num_pages
));
endif;
?>
</div>
FUNCTION.PHP
function tourcat_ajax_by_order() { if (isset($_REQUEST)) {
$posts_per_page = et_get_option( 'divi_archivenum_posts' ) ;
$args = array( // WP query args
'post_type' => 'tour',
'post_status' => 'publish',
'posts_per_page' => $posts_per_page
);
$tour_query = new WP_Query($args);
if ( $tour_query->have_posts() ) { // Have posts start here
while ( $tour_query->have_posts() ) { // While starts here
$tour_query->the_post();
?>
<span> <?php the_title(); ?> </span>
<br>
<?php}
echo paginate_links(array(
'total' => $aboutPosts->max_num_pages
));}
else {
echo 'No results found';}
wp_reset_postdata();}
die();}
JS CODE
function tourcat_orderby_posts() {
$.ajax({
url: ajaxurl,
data: {
'action':'tourcat_ajax_by_order',
},
success: function(data) {
// This outputs the result of the ajax request
$(".tour_parent_div").html(data);
},
error: function(errorThrown) {}
});}

似乎你想在没有重新加载页面的情况下使用ajax获得结果，以下代码可能有所帮助：希望这会有效
paginate，js：
$('.pagi').on('click',function()
{
var pageid=$(this).data('page');
var page_total=$(this).data('total');
var data={
action: "ajax_by_order",
pageid: pageid,
page_total:page_total
};
$.post(sitesettings.ajaxurl, data,function(res){
var cont = JSON.parse(res);
$('.result-content').html(cont.html);
$('.pagin').html(cont.pagination_html);
});
});
Function.php
function paginate_script() {
// Correct the path and js file name before using.
wp_enqueue_script( 'paginate', get_stylesheet_directory_uri() . '/js/paginate.js', array(), '1.0', true );
wp_localize_script( 'paginate', 'sitesettings', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
));
}
add_action( 'wp_enqueue_scripts', 'paginate_script' );
add_action('wp_ajax_nopriv_ajax_by_order', 'tristup_ajax_by_order' ); //witout logged in
add_action("wp_ajax_ajax_by_order","tristup_ajax_by_order"); //logged in
function tristup_ajax_by_order()
{
$page_id=$_POST['page_id'];
$page_total=$_POST['page_total'];
$args['post_type']='tour';
$args['post_status']='publish';
$args['posts_per_page']=3;
if($page_id>0)
{
$args['offset']=(3*$page_id);
}
$aboutPosts = new WP_Query($args);
$output='';
$pagination_html='';
if ( $aboutPosts->have_posts() )
{
while ( $aboutPosts->have_posts() ) : $aboutPosts->the_post();
$output.='<div>'.get_the_title().'</div>';
endwhile;
}
for($i=0;$i<$page_total;$i++)
{
$j=$i+1;
$pagination_html.='<span><a href="javascript:void(0);" class="pagi" data-page="'.$i.'" data-total="'.$page_total.'">'.$j.'</span>';
}
$result['html']=$flag;
$result['pagination_html']=$pagination_html;
echo json_encode($result);
die();
}//end of function

这未正确实施，您可以尝试以下方法：
<div class="site-content clearfix">
<h1>Alex Blog</h1>
<div id="page-posts-wrapper">
<?php
$ourCurrentPage = get_query_var('paged');
$aboutPosts = new WP_Query(array(
'post_type' => 'tour',
'post_status' => 'publish',
'posts_per_page' => 3,
));
if ($aboutPosts->have_posts()) :
while ($aboutPosts->have_posts()) :
$aboutPosts->the_post();
?>
<span> <?php the_title(); ?> </span>
<br>
<?php endwhile;
echo paginate_links(array(
'total' => $aboutPosts->max_num_pages
));
endif;
?>
</div>
</div>
function custom_assets_39828328() {
// Correct the path and js file name before using.
wp_enqueue_script( 'ajax-pagination', get_stylesheet_directory_uri() . '/js/ajax-pagination.js', array(), '1.0', true );
global $wp_query;
wp_localize_script( 'ajax-pagination', 'ajaxpagination', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
'query_vars' => json_encode( $wp_query->query )
));
}
add_action( 'wp_enqueue_scripts', 'custom_assets_39828328' );
/**
* AJAX Pagination function
*/
function my_ajax_pagination_72372732() {
$query_vars = json_decode( stripslashes( $_POST['query_vars'] ), true );
$query_vars['post_type'] = 'tour';
$query_vars['paged'] = $_POST['page'];
$query_vars['post_status'] = 'publish';
$query_vars['posts_per_page'] = 3;
$posts = new WP_Query( $query_vars );
$GLOBALS['wp_query'] = $posts;
if( ! $posts->have_posts() ) {
echo 'No results found';
}
else {
while ( $posts->have_posts() ) {
$posts->the_post();
?>
<span> <?php the_title(); ?> </span><br>
<?php
}
echo paginate_links(array('total' => $posts->max_num_pages ));
}
die();
}
add_action( 'wp_ajax_nopriv_ajax_pagination', 'my_ajax_pagination_72372732' );
add_action( 'wp_ajax_ajax_pagination', 'my_ajax_pagination_72372732' );
(function($) {
function find_page_number(element) {
element.find('span').remove();
return parseInt(element.html());
}
$(document).on('click', 'a.page-numbers', function(event) {
event.preventDefault();
page = find_page_number($(this).clone());
$.ajax({
url: ajaxpagination.ajaxurl,
type: 'post',
data: {
action: 'ajax_pagination',
query_vars: ajaxpagination.query_vars,
page: page
},
success: function(html) {
$('#page-posts-wrapper').empty();
$('#page-posts-wrapper').append(html);
}
})
})
})(jQuery);
你也可以用这个（可选）替换ajax回调查询args：
$new_args = array(
'post_type' => 'post',
'post_status' => 'publish',
'paged' => $_POST['page'],
'posts_per_page' => 3,
);
在两种情况下均可使用。
